Typical Suspension Methods - Space-Ray ADU25 Installation And Operation Instruction Manual

TYPICAL SUSPENSION METHODS

Not withstanding their limited scope, the appliance should be installed in accordance with the relevant
provisions of any National Gas Safety (Installation and Use) Regulations. Due account should also be taken of
any obligations arising from any National Heath and Safety at Work Regulations, National and Local Building
Regulations and National Electrical Wiring Regulations. The appliance must be installed, and where necessary,
converted for use on other gases, by a qualified installer.
Various means of suspending the heater can be used. See the following drawings for typical examples.
Use only noncombustible materials for suspending hangers and brackets.
a.
Linear Tube Heaters should be suspended to provide a slope of 0.25 degree up to the fan (25 to 50mm). The
b.
appliance should be located with respect to building construction and other equipment to permit access to
the appliance for servicing etc.
U-Tube Heaters should be suspended horizontally along the length.
c.
Turnbuckles can be used with chains to allow leveling of the heater. All "S" hooks and eye bolts must be
d.
manually crimped closed by the installer.
For suspending the appliance it is recommended that suitable protected welded chain (Ø 3mm x 65 links
e.
per m) or Ø 8mm min mild steel drop rods and suitable brackets are used. Attach the chains or drop rods to
the hanger brackets where shown providing at least Ø5mm closed link hooks are used chains may be
attached directly to the hanger brackets.
Heaters subject to vibration must be provided with vibration isolating hangers.
f.
Heaters must not be supported by gas or electric supply lines and must be suspended from a permanent
g.
structure with adequate load capacity.
The appliance may be mounted horizontally or at a recommended angle of 30
h.
Hanging points are fixed along the length of heater to accommodate trim pieces. Secondary steel work may
i.
be required to span between supporting beams.
The appliance should be located with respect to building construction and other equipment to permit access
j.
to the appliance for servicing etc.
Space-Ray recommends that the body sections be suspended using chains with turnbuckles. This will allow slight
adjustments after assembly and heater expansion/ contraction during operation.
If a "trapeze" method is used for tube support/hanger brackets (shown below), the minimum chain length for the
two connecting chains is 914 mm to minimize any vibration that might be generated by the draft inducer
assembly. If these chains must be less than 914 mm, then do not use the trapeze method and, instead, use
individual chains on each tube support/hanger bracket.
IMPORTANT: When U-Tube Heaters are angle mounted (see Fig 19) the fan should be assembled to the higher of
the two emitter tubes as shown.
